In the context of the booming photovoltaic industry, the influence of global photovoltaic brands has become increasingly prominent. Recently, the 9th CPC2024 Century Photovoltaic Conference and the 12th PVBL Global Photovoltaic Brand List Conference were grandly held in Shanghai. With its outstanding technical strength and brand influence, ESTUN successfully ranked among the top 100 global photovoltaic brands in PVBL 2024, demonstrating its strong technical strength and market position, and further enhancing its brand influence and popularity.

At the 17th International Solar Photovoltaic and Smart Energy (Shanghai) Conference, ESTUN demonstrated its complete intelligent manufacturing solutions with its leading position and innovative capabilities in the field of intelligent manufacturing, and worked with partners to promote the sustainable development of intelligent manufacturing and digital ecology.

Focusing on the application technology of the entire photovoltaic industry chain, ESTUN has been working hard to create a complete intelligent solution for the photovoltaic industry around the intelligent manufacturing needs of each process segment of silicon crystals, battery cells, and photovoltaic modules.

Robot + complete application solution

For the photovoltaic industry, ESTUN has reached close cooperation with more than 100 photovoltaic companies. The complete solution of intelligent manufacturing in the entire industry chain is applied to various photovoltaic process stages, providing intelligent and complete solutions for the photovoltaic industry and applications, and leading the vigorous development of the photovoltaic industry with Chinese technology.

ESTUN has been deeply involved in the photovoltaic industry for many years and is familiar with every process from silicon materials and wafers to battery cells and packaging. While helping customers to improve robot automation, it customizes high-value products for difficult processes, breaks through application difficulties, and achieves production line coverage of the entire process chain of the photovoltaic industry.

In the silicon rod handling process, in view of the process requirements of large size, silicon rod handling, glue coating, etc., ESTUN ER220B-2650/ER280-3200/ER350-3300 and other heavy-load six-axis robots are used. Combined with the advantages of high anti-interference, high-beat, high-stability, multi-station solutions are realized, which are compatible with the processing of silicon rods with different cross-sections of 182mm or 210mm, and meet the production needs of different types of work with different loads.

In the field of battery cell insertion, in response to the trend of thinner and larger battery cells, ESTUN customized the ER35B-1810-LI robot for ALD insertion and launched the UNO-15-1430-HP robot for PE insertion, which can carry 34 battery cells in a single cycle. Through the new key parts selection + rigid body design + vibration suppression algorithm, the product accuracy is improved to meet the application of insertion. At the same time, the full-axis rigid transmission, equipped with advanced dynamics models, realizes the global optimal acceleration and deceleration planning and accuracy guarantee, which can effectively prevent the risk of battery cell scratches.

In the field of cell layout, ESTUN is developing the ER20B/10-2010-HI high-speed, high-inertia robot in response to the needs of users in the photovoltaic industry, equipped with a high-precision visual system for laying out component battery strings. With the self-developed layout-specific software package, it can easily switch layouts in 10 minutes, and the single-string cycle can reach 3.2s/string. The production efficiency is world-leading, helping photovoltaic battery companies to increase the production line utilization rate of the string layout process to more than 98%. The large inertia and 2010mm long arm span are easily compatible with various layouts. The integrated visual control solution is adopted, and the visual operation of the teaching box makes debugging more convenient. The local communication method is adopted, and the communication delay is reduced by 30%, which solves the problem of flexible production and high-efficiency transition of photovoltaic companies in product switching.

Motion Control Products

ESTUN is committed to providing users with more professional motion control solutions to meet their diverse application needs, improve efficiency, and create value for users. In the field of motion control, ESTUN has comprehensive motion control products and world-leading motion control technology. Through the Cuiou motion control platform, servos, inverters, sensors, robots and other systems are better integrated, so as to flexibly and quickly build a set of professional motion control solutions for users.
